To all whomtt mag concern: I Be it known that ll Chauncey B.Foawere,citizen of the nited States, residing at Urbana, in the county ofChampaign and State of Ohio, have invented certain new and usefulImprovements in Apparatusfor vaporizing Hydrocarbon Oils, of which thefollowing s a specificatmn. f

This invention relates to an apparatus for vaporizing hydro-carbon oils,all subticularly pointed out in the claims.

In the accompanying drawings, vFigure 1 is a vertical longitudinalsectional elevation of the apparatus, and Fig. 2 is a sectional plan online 22, Fig. 1. Fig. 3 is a cross section substantially on line 3-3,F1g. 1,

and Fig. 4 is a front elevation of the complete installation. 4

The conception herein embraces-the apparatus more or less asa whole anddetails of fllene may be derived from the vaporized product in suchsubsequent treatment as may be had by condenser or otherwise.

As herein shown A represents the wall of the furnace and a, b and 0 thevaporizing sections or parts of the retort proper. The said sections orportions are each double, in a sense, as there is an inner tube or pipe2 for-the oil and an outer tube or pipe 3 forming a jacket about thesame for superheated steam. These sections and the inclosing wall of thefurnace may have any suitable length, say twenty feet, more or less,.andthe said sections are set at such inclination in respect to each otheras to provide continuous drain or flow by gravity of any possibleunvaporized substances through the same.

The said sections also are continuous one with the other from a tob andb to 0 by means of elbows or joints d and d at their ends, but the saidelbows or joints are exspecification of Letters Patent.

steam jackets 3 as seen more especially in charging at 5 at the rear of.the retort.

From this point the vapors are taken off for subsequent treatment incondensers or The said elbows also are removable so as to-make itpossibleto reach and remove any one of the pipes 2'without disturbingother parts. 1

llt will be noticed that the outer or jacket pipes 3. of the saidsections terminate substantially at the wall of the furnace, and

have annular flanges or rings 6 just outside said wall at their endswhich are bolted to a collar S'sleeved on oil pipe 2, and which collarhas a packing gland within the same about pipe 2 and adapted to betightened by another collar 10 which is adj ustably bolted to thepacking collar 8 and has a portion bearing against the packing undercollar 8 to tighten the same. This provides for unequal expansion andcontraction in said pipes or tubes, as unavoidabl occurs, and which hastobe taken care of 1n this way to avoid leakage of steam. As to thistendency .of the steam to leak it should be understood that theexceedingly'high temperatures employed are such that the said retortsections will become red hot. Hence the importance.

expand without disturbing the packing be- 1 tween them and withoutleakage, and the outer pipes 3 are facilitated in longitudinal expansionand contraction by rollers 12 on which they rest at their front ends andhave free lon gitudinal .movement.

The furnace is shown as heated by means of oil by pipe 9 and superheatedsteam by pipe 11, and the steam employed in the retort for heating theoil therein flows from the boiler through pipe 15 and the coils 16 vPatented Feb. 5, let... Application filed February 5,1916. serialno.76,376.

therewith in the furnace and which are exposed to the superheatingtemperatures therein as also are the said retort sections. From thesecoils the superheated steam flows by the extension of said coil pipethrough the side of the furnace wall to the union 17, which is purposelyplaced outside at this point to enable the coils 16 to be disconnectedand removed when for any reason-this becomes necessary, and whichremoval is very liable to become necessary on. account of thehigh heatto which they are subjected. From the said'outside union or joint 17 thepipe returns within the furnace again by connection 19 to joints 20 atthe front of pipe 21 to the several steam distributing pipes 22, 23, 24and 25 to the steam jackets of the said several retort sections a, b and0: Each of the three down pipes from pipe 22 'to said sections isprovided with a hand controlled valve 26, and pipe 22 has a blow-out 26and a pressure gage 27 surmounts pipe 21.

Oil is supplied to the retort for vaporizing from a head or supply whichemplovs a force pump,not shown, and the oil is driven under therequisite pressure through pipe 30 to a preheater or superheater 31located -over the wall or top of the furnace and running the full lengththereof from rear to front. The said superheater has an oil carryingpipe 32 on its inside and a pipe 33 about the same providing a jacket ofsuperheated steam for said oil pipe. The pipe 33 is wrapped heavily withasbestos or the like to confine the heat, and oil flows into the rearend of the superheater by pipe 30, while superheated steam from the rearends of vaporizing sections a b and c flows into the jacket 33 of thesuperheater by pipes 35 and'36.

From the superheater 31 the oil flows to the upper of the several retortsections by pipe 37 through an atomizing nozzle 40 at its front end andsuperheated steam from the superheater likewise enters the atomizer withthe oil by pipe 38 and in such manner as to contribute most effectivelyto the vaporization and dissemination of the oil vapors with the steam.In fact, however, the oil is not only vaporized in the superheater butthe vapors thereof are heated to a very high temperature so that whenthe oil vapors reach the atomizer 40 and enter the retort with thesuperheated steam they are in a state to commingle thoroughly therewith,

, and the said vapors and steam traverse the said retort sectionstogether and issue in a superheated state from section 0 at the exhaust,5 to the condensers or separators next in order.

By building the retort-in sections as shown of ma follow as shall bedeemed desirable,

and o viously, there will be ultimate condensation and separation butthe means for this purpose do not constitute a part of this invention.

What I claim is:.

1. The apparatus described comprising a furnace chamber, a plurality ofretort sections in said furnace consisting each of an inner tube for oiland an outer tube for a steam jacket, the said outer tubes terminatin'with the furnacewalls and the inner tu es extending beyond the wallthereof, packing for said outer tubes on said inner tubes and jointsconnecting the ends of the inner tubes outside the furnace wall.

2. An apparatus as described, comprising a furnace, a plurality ofretort sections exposed in said furnace on different horizontal planesand having inner oil tubes and outer superheating jackets terminatingwithin the ends of the inner tubes, removable tubular joints connectingthe ends of said inner tubes outside the wall of the furnace and anatomizer in the end of the upper of said sections to inject oil andsteam together therein.

' 3. An apparatus as described, comprising a furnace and a sectionalretort therein consisting of oil pipes extending through the wallsthereof and steam jackets terminating at said walls having annularflanges at their ends and collars next to said flan es on said. oilpipes provided with packlng glands, and elbow joints connecting the endsof said oil pipes outside said glands, whereby expansion of said pipescan occur without causing leakage of the steam from said jackets.

4. In an apparatus as described, a plurality of retort sections openlyconnected at their ends and having steam heating jackets between theirends, in combination with an oil heater having a steam jacket openlyconnected by separate pipes with the jackets of said retort sectionsrespectively.

5. In an apparatus as described, a plurality of retort sections atdifferent elevations and provided with oil carrying tubes open one tothe other at their ends and provided with steam jackets betweentheirends, in combination with a tubular oil heater having a steam jacketabout the same and pipes from the jackets of said retort sectionsdischarging into the jacket of said oil heater, and pipe connectionsfrom said rero teoil heater and the jacket thereon arranged to dischargetogether into the upper of said retort sections.

6. In an apparatus as described, a, retort consisting of inner and outertubes spaced apart to form a jacket between them and means providing forunequal expansion of said tubes comprising a packing for the ends of theouter tube about said inner tube and in which said inner tube isslidnbie, and W rollers supporting the corresponding end of the outer ofsaid tubes behind said packing.
